METAL BARREL-HOOP.

SPECIFICATION forming part of Letters Patent No. 653,707, dated July 17, 1900.

Application filed June 8, 1899. Serial No. 719,767. (No model.)

To all whom it may concern.-

Be it known that I, FRANKLIN B. SHUSTER, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Metal Barrel-Hoops, of which the following is a specification.

My invention relates to an improvement in metal barrel-hoops; and it consists in forming retaining-points on the inner circumferential surface of a metal hoop, so that such points will engage with the outer surface of the staves and prevent the accidental displacement of the hoop.

To enable others to understand my invention, reference is had to the accompanying drawings, in which Figure 1 represents a broken section of a barrel-hoop made of round wire, showing retaining-points projecting from the inner surface thereof. Fig. 2 is a perspective view of a barrel with two metal hoops attached thereto. Fig. 3 is a broken detail upper plan view of a section of the metal hoop. Fig. 4 is a broken detail sectional View of a barrel-stave and section of the wire hoop through line (L a of Fig. 3. Fig. 5 is an end elevation, partly in section, of a pair of rolls for forming the retaining-points on the hoop with a section of a hoop between such rolls.

The construction and operation are as follows:

1 represents the hoop, made of round wire, and 2 are the retaining-points, and 3 the barrel-staves, The points or barbs are formed on the inside surface of the wire hoop in an economical manner by means of the rolls 4 and 5. The appurtenances-such as housings, shafts, &c.for these rolls are omitted, as their construction is well known. 6 and 7 are semicircular grooves around said rolls, and 8 are tooth like projections at the bottom of the groove of the upper roll. The wire to form the hoop is passed through these rolls and the projections 8 embed themselves in the body of the wire and force out the stock to make the spurs or barbs 2.

Heretofore hoops have been made of round wire and these secured to a barrel by means of staples, as the round wire will not hold without something of this kind to prevent its slipping up the stave. This extra expense both in material and time in attaching such staples is quite a serious objection to the general adoption of the hoop made of round wire, although such a hoop is decidedly stronger than the old wooden hoop or the wide fiat hoop. lVith my improvement the extra cost of forming the barbs is immaterial, as this will be done when the hoops are made. In forcing the hoop onto the barrel the barb 2 will lie against the staves, as shown at Fig. 4. The force necessary to drive the hoop into place will naturally put a torsional strain on the wire in the direction as indicated by the arrow 6, so that when the hoop is in place the strain will be in the direction indicated by arrow 0, which will tend to crowd the barb 2 toward or into the stave and prevent its working up accidentally. In fact, it would require considerable force to drive the hoop upward from its seat.

I do not wish to be confined to the shape of the barbs or spurs nor to the manner of forming them. The gistof my invention lies in forming a spur or retaining-point from the body of the wire hoop and integral therewith and on such portion of the hoop as will bring such spur or retaining-point in contact with the barrel-staves.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The herein-described improved barrel-hoop consisting of a hoop constructed of round wire and having a series of retaining-spurs formed integral with body portion of said wire so that,

when the hoop is forced down the inclined surface of a barrel, it will impart a torsional strain on said round wire hoop and thus tend to throw the said spurs outward, and when the hoop hasreached its resting-place, such stored-up tension will react and force said spurs into the barrel-staves, for the purpose set forth.

Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 7th day of June, A. D. 1899.

FRANKLIN B. SHUSTER.
